The present invention relates to a method of transferring goods with turned over edge to a transfer or welt bar.

In order to connect knit goods with goods I of another class, such as warp goods and the like, or with goods of a different gauge, it is generally known to turn the part to be transferred to a hosiery or knitting machine over at the edge to bepicked up and to transfer it 0 thus to the needles of the machine, which will then pass through the two layers of the transferred part. The transfer itself may be prepared by means of a transfer device of known type involving the arrangement of the goods 5 on a regular transfer or welt bar, so that the goods need merely to be transferred to the needles of the hosiery or knitting machine. The most diflicult feature of the transfer operation' consists, however, in the necessity of transferring the doubled portion of the goods as closely as possible to the turned over edge, which is quite a wealrisome task and one which re uires considerable skill.

ccording to the invention, these diflicul- 5 ties are eliminated by disposing the part to be transferred on the fixed edge of a holding memberrecessed at uniform small distances, the part hanging down on both sides of the edge and being pierced by a welt or transfer 'bar at the edge while the bar is introduced into the part at the-recesses of the fixed edge. The special device for carrying out this method consists, according to the invention, of a buckled or cranked needle bar or of a. groo'yed plate in connection with an ordinary welt or transfer bar. The method according to the invention accelerates the transfer process considerably and produces a very accurate transfer line close to the doubled edge. Two forms of the invention are illustrated in the accompanying drawings.

Figure 1 is a front view of the part to be transferred. Figure 2 is an oblique view of a cranked or buckled needle bar.

Figure 3 shows how the part shown in Fig. 1 is arranged on the bar shown in Fig. 2..

Figure 4 shows how the picked up part filings down on both sides of the transfer 6,

Figure 5 shows how a second bar for receiv- Figure 9 shows how the part to be transferred is secured to the grooved plate shown in Fig. 8.

Figure 10 indicates how the part to be transferred is pierced by a common hook barand thus secured to this bar.

Figure 11 shows how the attached part is removed from the plate shown in Fig. 8 by means of a welt bar.

Figure 12 shows how tubular goods can be set on a welt or transfer bar,

Referring to the drawings, the part 1 o the goods to be transferred to a hosiery, knitting or looping machine is'set alongthe line 2 on the pointed hookless needles 3 of a trans-- fer bar 4. The needles 3 are preferably provided with the buckles 5 which-keep the part 1 at a uniform height and on both sides of which the goods hang down, as shown in Figs.

3 and 4;. In this way the ed e of the part 1 can be hooked on very close y, since'it will yield downwardly in the direction of the needles 3 between the buckles 5 by the pres-. sure of the bar 7.

Being transferred, the part 1 drops down on both sides of the transfer line 2 (Fig. 4)

whereupon a welt bar 7 provided with the hanging-in needles-6 is introduced vertically to the plane of the needles 3 and parallelto the line 2 between the needles :3 of the bar 4 and the bar 7 is pressed down and withdrawn in the direction of the arrow in Fig. 5 so as to cause the hooks 8 of the needles 6 to enter the loops of the part 1 on one side and, ,s1multa-' neously, to pierce the other side of the goods. The hooks 8 of the needles 6 engage therefore the part 1 twice, and the next ste is to bring the bar 7 into an almost perpen 'cular position and to lift it so that the part 1 is taken off from the needles 3 of the bar 4 and held merely by the hooks 8 of the needles 6 of the welt bar 7 (Fig. 6). The part 1 is now in a condition that only the portion held by the hooks 8 need be pushed rearwardlyover the latter, and, together with the other portions, along the? stems of the needles 6 towards the bar 7 when the goods can be set on the needles of a hosiery, knitting or looping machlne 1n the known manner, the procedure resembling the one employed when tickling ofl a welt on a full fashioned hosiery machine of the cotton system or when transferring legs of stickings to a cotton footing machine.

Instead of the bar 7 fitted with the hooked needles 6 a bar may be used having the hookless or spring needles 9 and-being introduced like the first bar vertically to the plane of the needles 3' and parallel to the transfer line 2 between the needles 3, the bar piercing the part 1 twice in succession, which hangs down 7 on both sides of the line 2. If provided with the hookless needles 9 the bar 7 is pushed in this horizontal position upwardly along the needles 3 and the part 1 is lifted off from the bar 4. The goods 1 can then betransferred from the'bar 7 with its hookless needles to the needles of a hosiery or looping machine.

The vertical bar 4 can be replaced by a plate 11 with the grooves 10 or, in circular knitting machines, by a ring, the part 1 to be transferred being then stretched over the edges 12 and fixed in position by hand by means of the hooks 13 provided above and below the plate 11. By means of a bar 14 fitted with the spring needles 15 the part 1 is then set on the edge 12, the needles 15 of the bar 14 passing,

through the goods between the grooves 10, or the part 1 is hooked on the edge 12 by means of a bar 17 provided with the hooked needles 16, so that the hooks 18 of the needles 16 pass twice through the part 1.

As the part of the goods to be brought on to the welt or transfer bar may be set on at will, the method described can be applied not only to ordinary knit goodsbut also to close goods, such as warp and woven fabrics.

By means of the two devices described it is further possible to transfer tubular goods to a welt ortransfer bar by making use of a needle bar/4, as shown in Fig. 12, the tubular goods 1'9being simply placed over the bar 4 from the side and then drawn down from above over the needles 3, so that the latter enter the goods 19. The goods 19 will then hang down on both sides of the transfer line and can be hooked up by awelt or transfer bar and removed from the bar 4 in the man ner described above. This method is particularly adapted for working a top on to a garment, such as a stocking.

I claim a 1. A method of setting a piece of goods with turned overxedge on a welt or transfer bar, comprising placing the part to be transferred on a fixed edge of a holding device, the said edge being recessed at uniform distances,

the part to be transferred hanging down on 3. A device for setting a piece of goods with turned over edge on a welt or transfer bar as described, comprising a transfer bar, a plurality of buckled needles arranged on the said bar and penetrating the piece to be transferred and a second bar introduced vertically to the plane of the needles and parallel to the longitudinal axis "of the said first bar, the said second bar positively penc trating first one and then the other layer of the picked up piece hanging down on both sides of its transfer line closely to the latter.

4. In a device of the character described, a grooved plate, the piece of goods to be trans- 'ferred being stretched over said plate, a bar, and a plurality of needles carried by said bar and adapted to penetrate through said piece.

5. A method of transferringgoods, comprising the steps of placing a piece of goods to be transferred on. a holding member, the part of said member nearest to said piece being recessed, and introducing the projections of another member into said piece at the recesses of the first-mentioned member. s

In testimony whereof, I have aflixed my signature.
